Tool modifications enable quick mobilization on West Africa project Subsea repair of pipelines in deepwater is a complex and challenging operation that involves the use of remotely operated vehicles (ROVs) to deploy specialized tooling, clamps, and connectors. Pipeline repair also requires the engineering, logistics, and deployment of a range of other equipment, including pipe lift ...

According to Transportation Secretary Ray LaHood, more than 2.5 million miles of pipelines are responsible for delivering oil and gas to communities and businesses across the United States. Much of the pipeline network is old and in a state of disrepair. The Obama Administration launched on April 4, 2011, a national pipeline safety initiative to repair and replace aging pipelines to prevent ...

ABSTRACT According to one estimate there is over 4.2 billion feet of wastewater pipeline in the United States. The nation’s sanitary sewer system is increasing in size and the existing infrastructure is aging. Currently, there are almost 20,000 municipal collection systems building and maintaining these critical pipelines. A good portion of the pipe conduit is under attack by one or more of ...

Time, budget and resources often keep a municipality from maintaining comprehensive, up-to-date information on water and sewer pipeline conditions. Without a complete understanding of their infrastructures, municipal supervisors cannot properly prioritize and schedule maintenance activities. As a result, emergencies—backups, collapses, and overflows—happen unexpectedly, and must be dealt with on ...

The San Diego County Water Authority got the call at midnight on May 16, 2006. One of themajor water delivery pipelines in Mission Trails Regional Park in San Diego had burst, resulting in millions of gallons of water rushing through the park. It was over the next several hours that the Water Authority’s community outreach began. Within days the project was declared an emergency and the Water ...

For effective management of water and wastewater infrastructure, the United States Environmental Protection Agency (US-EPA) has long emphasized the significant role of risk in prioritizing and optimizing asset management decisions. High risk assets are defined as assets with a high probability of failure (e.g. soon to fail, old, poor condition) and high consequences of failure (e.g. ...

For utilities with large-diameter networks, waiting for failures to occur before repairing or replacing highly critical mains is not an option. With a large amount of buried water infrastructure reaching the end of its service life, operators have every incentive to take a proactive approach to asset management. Nowhere is this more critical than in busy urban centres. The fallout from an ...

Underground pipelines are among the most valuable, yet neglected assets in the public arena. They provide essential services such as the supply of drinking water and collection of wastewater. Despite their critical importance, for decades many municipal utilities have operated under a “bury and forget” mentality – with little emphasis on long-term management of their aging ...

Utilities across the country are experiencing an increased rate of pipeline failures. In addition to problems precipitated by an aging water infrastructure, a lagging economy is affecting large-scale capital projects needed for repairing, replacing, and improving infrastructure. With funding gap estimates ranging between $200 billion and $1 trillion over the next 20 years, utilities must find ...

Assessing the condition of buried water infrastructure can yield a variety of outcomes that are difficult to predict. Sometimes, they even seem random. The common belief that the age of a pipe determines its condition is rarely correct – in many cases, a newer main can be in worse condition than one twice or three times as old. Instead, operational, environmental and installation factors ...

Because pipeline systems represent more than 80% of the total asset value of water-distribution systems, their management is an important issue for water utilities. A pipeline deteriorates over time after installation and, along with the deterioration, pipe bursts can occur as various types, and the choice of a maintenance and repair strategy will depend on the burst types. It is therefore ...

Abstract Various governmental, professional and private studies have shown that the replacement costs of underground pipeline infrastructure is excessive and that best practice approaches for infrastructure risk management promote condition assessment programs to understand the actual condition of individual pipe sections in order to best allocate limited capital replacement and ...

As with any maturing technology, the inspection crawler market has evolved from a handful of basic models to a vast array of configurations, each uniquely adapted for nearly any pipeline inspection application.For buyers, this can also be a double-edged sword since finding the right crawler among the myriad of choices can require research, forethought, and inevitably some compromise. So, here are ...

Maximizing the life of aging pipelines has long been a challenge in North America. Owners of large diameter water and wastewater infrastructure face particular condition assessment challenges, owing to factors such as financial constraints, environmental concerns and access restrictions, which compound the problem. While desktop studies can help identify pipes with a likelihood and consequence of ...

Regulatory compliance at the state and federal level grows infinitely more complex when the laws and regulations of six U.S. states, U.S. federal regulations, and the Canadian regulatory regime are intertwined. TransCanada’s proposed Keystone XL Pipeline, currently awaiting approval from the U.S. Department of State, is gaining as much attention for its regulatory ...

Global’s Cougar and Falcon ROV systems were mobilized to Hawaii to facilitate repairs on the 40” coldwater pipeline transition section in 500 feet of water off of Keahole Point on the island of Hawaii for the Natural Energy Laboratory of Hawaii Authority (NELHA). ...

According to an adapted Murphy's Law, "anything that can fail, will fail." While that universal engineering law has been proven true again and again, many utilities are working diligently to reduce the risk of failure by taking measures to improve the service life of their aging ...

A Trenchless Repair for sewer pipes has been trending in parts of the country. It allows for pipes to be fixed or replaced without trenches being dug into the yard or landscape. It also allows the problem to be fixed without the mess of digging up existing structures such as; porches, driveways, sidewalks, and much more. It is important for business’s who advertise the Trenchless Repair to ...
